・Always tighten the bolts at the specified torque. If the torque is insufficient or excessive, the bolt will break, which
is dangerous as the chuck or work will fly out.
・Use the bolts attached to the chuck, and do not use other bolts. However, if you must use other bolts not
provided by Kitagawa, use bolts that have at least a strength classification of 12.9 (10.9 for M22 or more) and be
sure they are long enough.

・When attaching the draw pipe to the cylinder, the stopper pin of the piston may break if tightened at the stroke
middle position of the piston. In the case of a YW type cylinder, screw it in so that the piston rod is fully in. Follow
the explanation of the instruction manual for the cylinder for other items about the cylinder.
・Determine the dimension (dimension φA in Fig.18) of the back plate so that the plunger nut end surface contacts
the back plate and stops when pulling the plunger nut. If the stroke is larger than the one specified, it may cause
a chuck breakage or gripping failure.

・Remove the eyebolt or the belt without fail after using. If the chuck is rotated with the eyebolt, etc., attached, they
may fly out and this is dangerous.

1. Attaching the draw bar and draw pipe to the cylinder
・Apply adhesive onto the screw part of the draw bar and the draw pipe, and screw it into the piston rod of cylinder. At
this time, refer to the instruction manual for the cylinder for tightening torque.
2. Attach the cylinder to the spindle (or the cylinder adapter)
・Check the run-out of the cylinder, and if it is normal, attach the hydraulic pipe.
・Move 2 to 3 times at low pressure (0.4 MPa-0.5 MPa, 4 - 5 kgf/cm
2
) and set the piston at the forward end and turn off
the power supply.
3. Attach the chuck matching to the attaching surface of the spindle (or the back plate).
・Remove the soft jaw and the cover then remove the plug with the handle.
・In the case of adjusting the centering of the chuck, lightly hit the body side face with a plastic hammer.
・Tighten the chuck attaching bolts evenly. At this time, tighten the bolts at the specified torque.
4. Connect the chuck to the draw bar and the draw pipe
・Joint the lock nut with the draw-pipe using the tightening handle. Then, tighten the lock nut locking screw.
・After installing the lock nut completely, tighten the plug until it hits against the plunger piston. Then, tighten the lock
screw until the draw-nut hits against the draw-bar.
・Do not forcibly screw them in if they cannot be screwed smoothly, but check the inclination of the core of the screw, etc.

・Use an eyebolt or a hanging belt
when attaching and detaching the
chuck to and from the machine,
as there is a danger of injury or
damage if the chuck drops.

5. Adjust the position of the plunger
・The appropriate position of the wedge plunger at the cylinder forward end is the position when the dimension A in
Fig.19 becomes as shown in the table below.
・At this time, check that the reference mark of the master jaw meets the line of the outside of the stroke mark. (Refer to
page 17).
・A click stop (rotation stopper) is also attached to the draw nut, so complete adjustment at the position where this
response is felt.
